Abstract: 391,003. Testing physical qualities of materials. SCHUMAG SCHUMACHER METALLWERKE AKT.-GES. FUR PRAZISIONSMECHANIK, 35, Hauptstrasse, and MATHAR, J., 44, Emmichstrasse, both in Aachen, Germany. Aug. 15, 1932, No. 22828. Convention date, Aug. 17, 1931. [Class 106 (ii).] Stresses in structional elements and completed structures are determined by applying a dilatation measuring instrument to the body to be tested, destroying a small part of the material in the immediate vicinity of the measuring points without impairing the body, and determining from the alteration produced in the distance between the reference points the stress prevalent at that position in the body. The instrument is mounted on the body under stress and a hole or cut made uear one reference point-for heavy structures a hole of about 6 mm. diameter and depth would suffice. The stress is obtained by reference to calibration curves obtained by applying the test to elements under known stresses.

Filed: 1945-09-11
Abstract: 621,679. Making magnetic cores. BRITISH THOMSON-HOUSTON CO., Ltd. Sept. 11, 1945, No. 23394. Convention date, Sept. 11, 1944. [Class 83 (ii)] [Also in Group XXXV] A laminated iron core for transformers and the like is made by bending pre-cut strips of magnetic material to part cylindrical shape and assembling them without the aid of a former into an annular core comprising two separable portions with interengageable ends. A core is made from two groups of strips 9, 10 which are given a permanent hemicylindrical set by passing them through rollers 14, the strips being assembled from inside to outside into a ring. Pins 20, 21 are passed through holes 11, 12 offset from the centre of the strips which are reversed in alternate layers, so that the laminations or groups of two or three laminations of each core half engage in staggered butt joints. Bands 23 are placed round the core which is given a rectangular shape by driving wedge 25 between tapered blocks 22 inserted in the core window. Pistons 26, 27, 28 pressing on the sides of the core may be used to assist in shaping the core without opening the joints, Fig. 7, and when the shape is satisfactory, plate 30 is welded to straps 31, 32 fixed to plate 29. The core is then annealed, disassembled and reassembled round the winding 5 (Fig. 9), rivet 32 being placed in holes 10, 11. The reassembly may be done a few sheets at a time if necessary. A core with staggered and butt joints in the yokes may be made from groups of laminations of equal length, and in assembly a magnetic holding device may be used, Figs. 12, 14 (not shown). The cores may be annealed whilst on their sides under pressure exerted by weights, Fig. 15 (not shown). In assembling cores which have joints in the yokes, around the coil, some laminations may have to be slightly bent, Fig. 16 (not shown). To avoid this the joint may be at opposite corners or the yoke only may be removable, Figs. 17, 18 (not shown). The winding 86 may be wound round two half cores 84, 85, Fig. 20. Specifications 7856/89, [Class 38], 621,675 and 621,677 are referred to.

Title: Improvements relating to the reinforcement of synthetic resinous materials and objects
Filed: 1937-08-26
Abstract: 501,649. Moulding reinforced synthetic resin. BRUYNE, N. A. DE, AERO RESEARCH, Ltd., and DE HAVILLAND AIRCRAFT CO., Ltd. Aug. 26,1937, Nos. 23434/37 and 9941/38. [Class 87(ii)] Reinforced synthetic material or objects having a large dimension relative to the crosssection, such as planks or rings, are made by placing lengths of resin-impregnated flax or linen rove in a mould that is kept hot as a whole or for a substantial part of its length for a certain time, and applying localized pressure for a less time, or transiently until the whole of the contents have been subjected to pressure. The compressed material or object is finally hardened in the mould by heat without pressure. In the form shown in Fig. 2, lengths of flax or linen rove that has been impregnated with phenol-formaldehyde resin and dried on a square-section openwork drum, is placed in a long open-topped mould 4 beneath a sheet 22 of steel. The mould is traversed step by step through a press having a heated platen 10 or plunger and a heated bed. The sides of the mould are protected from being forced outwardly by wedge members carried by the platen 10 and co-operating with inclined walls of the heated bed. In another form, the mould 31, Fig. 9, is placed in a heated member 32 and the material 30 is compressed beneath a flexible steel sheet 44 by a roller 34 of a weighted truck 35 guided on rails 38. Specification 470,331 is referred to. According to the first Provisional Specification, synthetic resin binder is used in such quantity that little excess is squeezed out of the impregnated material during the hot pressing operation. The resin may be applied in a volatile solvent. In some cases, impregnated threads are drawn through heated dies to remove the excess binder, or the excess may be taken up by interspersing unimpregnated material with the impregnated material. In other cases, threads are drawn through a small bath of fused resin binder and thence through a comb to remove the excess. Such threads are then formed into tapes by drawing them through a heated slit. Slivers may be encased in a metal gauze or perforated support during impregnation and drying, or the fibre, before going into the drawing frame, may be impregnated, and, as it leaves the frame, pressed by heated rolls. According to the second Provisional Specification, the trough in which the material is moulded may be jacketed for heating-fluid, and may be lagged with heat-insulating material. As impregnated rove is laid in the trough, further resin may be packed in.

Title: Improvements in or relating to valve rectifying and amplifying arrangements
IPC: G01R19/22
Filed: 1927-09-06
Abstract: 277,650. Siemens & Halske Akt.-Ges. Sept. 17, 1926, [Convention date]. Thermionic valve circuits.-A valve circuit for measuring small alternating currents and voltages comprises a resistance-capacity amplifier with a two-electrode valve V connected across its output resistance R. The current or voltage to be measured is applied to the grid circuit after preliminary application if necessary. The plate circuit includes a resistance W, and the plate is connected to the filament. through a condenser C, resistance R, and galvanometer J. The unilateral conductivity of the diode V practically shortcircuits the resistance R for one half-wave of the alternating voltage on the plate, thus giving a uni-directional current through the galvanometer. The initial voltage across the diode V is adjusted by a potentiometer P to bringing the working- point near to the straight rising portion of its characteristic, with the object of obtaining a linear relation between the input voltage and the resulting direct current. The Specification as open to inspection under Sect. 91 (3) states that the direct voltage arising across the resistance R may be applied to the grid of a further amplifier. This subjectmatter does not appear in the Specification as accepted.
